Refraction Flashcards
1
Q
When does refraction occur?
A
When the ray of light passes into a second medium. It only bends at the “boundary”, then it continues in a straight line
2
Q
What is Snell’s Law?
A
ni (sin θi) = nr (sin θr)
3
Q
Whats the refractive angle if the ray of light has a ni of 1.00, the nr is 1.33 and a θi is 75 degrees?
A
46.89 degrees
4
Q
What’s the refractive angle if the ray of light has a ni of 1.33, nr of 1.00 and θi of 84 degrees?
A
There is no refractive angle ( total reflection)
